the reduction of nonconjugated Δ²-isoxazolines to the corresponding β-hydroxy ketones using Al/CuCl2 as the reducing agent has been developed. The method is both rapid and complete requiring less than ten minutes to attain total ring cleavage. This is the first example of using an in situ prepared Al/Cu couple in organic synthesis. reduction - isoxazolines - β-hydroxyketones - aluminum/copper couple
已经开发出一种容易,经济和有效的方案,该方案使用Al / CuCl 2作为还原剂将非共轭的Δ2-异恶唑啉还原成相应的β-羟基酮。该方法既快速又完整,只需不到十分钟即可完成总的环裂解。这是在有机合成中使用原位制备的Al / Cu对的第一个示例。 还原-异恶唑啉-β-羟基酮-铝/铜对
